With the introduction of the fully electric i7, is the bell finally tolling for the gas-powered 7 Series? The V12 is gone and all that’s left is a plug-in hybrid system (483 horsepower, 55 km of zero-emission range) in addition to a 4.4-litre V8 with mild hybrid technology (536 horsepower). This full-size luxury sedan is absolutely packed with gadgets and amenities including a 31-inch BMW Theatre Screen for rear passengers and a 2,000W sound system.
